[0014] A further improved solution: The sliding part includes a first sliding piece and a second sliding piece, both of which are provided with the sliding groove. The sliding groove on the first sliding piece corresponds to the sliding groove on the second sliding piece, and the positioning block is located between the first sliding piece and the second sliding piece.

[0015] Based on the above technical solution, the dual-piece design of the first and second sliding plates significantly enhances the overall rigidity and stability of the sliding part. This design allows the sliding part to more effectively resist deformation and torsion when bearing the weight and operating force of the controller, thereby ensuring the stability and accuracy of the controller's position. The correspondingly designed grooves provide precise guidance for the sliding part, ensuring that the first and second sliding plates can slide synchronously and smoothly on the positioning block. Simultaneously, the elongated design of the grooves allows users to make fine adjustments within a wide range to meet personalized positional needs. This precise guidance and positioning mechanism makes the installation and adjustment of the controller simpler and more intuitive.

[0016] A further improved solution: the sliding part and the connecting part are an integral structure, and the connecting part and the mounting part are an integral structure.

[0017] Based on the above technical solution: The integrated structure design significantly enhances the connection strength between components, reducing the risk of failure caused by weak or loose connections. The sliding part, connecting part, and mounting part, as a whole, can better withstand the weight of the controller and various forces during operation, ensuring the stability and durability of the structure.
